CONSTITUTION:A position of a doctor unit 8 at the time of treating a patient in a seated position is set to a point A, while a position at the time of that in a laid position is set to a point B, and a vertex, in which the points A, B serve for the base, is set to a point C. An arc-shaped rail 9 is integrally provided with a base 7 on it with the point C serving as the center. Rollers and a bracket for mounting these rollers are engaged with this arc-shaped rail 9 and turnable with the arc-shaped rail 9 serving as a guide. In a side surface of a mounting side of the doctor unit 8, an opening 15 is provided to eliminate interference with a horizontal member 16a of an L-shaped strut 16 integrally provided with the bracket 14.
